Chargeable electric buses also have no emissions at street level, I don't know how long they last in comparison to the buses you mention, but I do know that batteries are unlikely to last the lifetime of buses where they only charge when stationary.
What I don't understand is why trolleybuses cost more than diesel buses.

Note that Amsterdam, Zürich and Strasbourg have trams, not trolleybuses. A single overhead wire above each track with rail return. Trolleybuses, with their rubber tyres, need at least two wires (and always an even number of them) for buses in each direction. So there is a very visible different between trolleybus and tram wiring.

Maybe that is unless other large vehicles, like trucks, could also be made to use the wires when driven along trolleybus routes. This doesn't mean they would be limited to the wires, see below.

Trolleybuses, like other electric vehicles, are not bound to any specific fuel source.
As far as I know, battery electric buses also need less maintainence
apart from battery replacement.

Wait, trams also run on wheels. And if trolleybuses can run off-wire on battery power for a limited time, trolley-trucks and other vehicles made to use these same wires would do the same, especially if they don't follow fixed routes.

Have they upgraded the wires?

Then the issue of the lines falling off, the buses are equiped with cords to reconnect to the overhead wires within seconds. Plus this only happens once in a blue moon.

Non-emergency vehicles that don't follow fixed routes should almost invariably give way to those that do. Giving way mean don't get in the way.

I don't know about ten years ago, but certainly battery buses are more popular than trolleybuses, even though all surviving first-generation tramways, with one cable-operated exception (in San Francisco), have overhead power throughout, and network-wide overhead power is also part of most new tram and light rail installations, is common on railways, and plenty of railways have been electrified with overhead wires even recently.
